Dryer drum light does not turn on when door is opened, but dryer otherwise works.

Safety first: Unplug dryer.

Steps:

• Replace bulb: Remove the drum light cover, unscrew the bulb, and replace with the correct type and wattage specified by LG.
• Check socket: Inspect for corrosion or loose connections; repair or replace socket if needed.
• Door switch: If light still does not work, the door switch light contacts may be faulty; replace the door switch.
